Hmm, let's do this later. It's good to cut dependencies on u-boot, but
having parallel mechanisms to determine the board version just leads to
madness.

In particular, the revision should be stored in a global variable, like
system_rev we have now, and then all references to system_rev should be
changed to that new variable.

Or, alternatively, we can just modify system_rev in gta02_machine_init.
